hey guys;
everytime getting the limp mode and scanning my car with the GT1 getting the code " 2A87 VANOS exhaust- stiff, jammed mechanically " it happens only when i drive with high speed and suddenly pushing the brakes, i get the half engine light popped up.... the worst part is that i got the exhaust vanos part changed, i changed many oil types and markets and still nothing changed, chain tension is exact, oil level is ok, both solenoid was replaced, Cam sensor is ok, i did everything related with the exhaust vanos repair troubleshooting, and i keep getting the vanos exhaust error on the GT1.... i was reading arround and there was a thread about rare camshaft issues can cause this, so i was wondering if this was my case

I was having a similar issue, but I would limp when I let out of it. A few other symptoms that I noticed were rough idle, loss of power at lower RPM's (below 3K), and poor fuel economy.

I took the car into BMW and told them my symptoms. They first changed the exhaust VANOS. I picked up the car, and before I got home car limped. Took the car back and they changed out the cam shaft (worn ledges).

Kanecyl , what do you mean ? if i replace both solenoid it's no sure that solve my problem ??

According to the dealer it could be a vanos problem,(less likely), it could be software problem(less likely) or it could be a camshaft problem(even more less likely. The solenoid is the most common. They have a way of testing it. It cost me 400 for them to do it I'm out of warranty

No he's talking about the vanos solenoid. There are two...one for the intake and one for the exhaust. There have been a large number of problems with them getting stuck or jammed. They usually clean and swap them to see if the problem persists or switches to the other solenoid.
